【摘要】 针对有源电力滤波器两种主要的控制方式偏差带控制和ＰＷＭ控制进行了仿真研究。对于（定）偏差带方式下偏差的选取给出了经验公式，讨论了偏差与平均开关频率之间的关系，并对这两种主要控制方式的补偿效果和优缺点进行了分析比较。仿真结果表明，偏差带控制方式更适合于有源滤波器的应用。这一结论对实际装置的研制有一定参考价值。更多还原

【Abstract】 y using the Krean program, the computer simulation of the constant-toleranceband control and the PWM control as two normal schemes for the active power filters arepresented. A practical formula for the option of the ripple current values and the relationship between the tolerance band and the average switching frequency are introdued. Thesimulation results show that the constant-tolerance-band control is more suitable for theapplication to the active power filters.更多还原
